Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deepgram

  • Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
  • Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
  • Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.

Temporal

  • Cloud pricing scales with action volume, with per-million overage fees ($50 per million initially)
  • Enterprise customers incur additional storage costs beyond base allocations
  • Self-hosted deployments require operational expertise to deploy and maintain the Temporal Service
  • No native workflow UI builder; workflows must be defined in code
  • Free tier limited to self-hosted option only; no free cloud tier
